Seems that when I make a model in rhino3d and save it to dxf, I open it and it does not appear in the screen. I have to locate it. The next issue, is making the dimensions. Dimension numbers font size is very tiny and hard to read. Also, How to properly align it next to x,y plane markings?
You've asked your question in the AutoCAD area of the forum. Is your question about AutoCAD or about Rhino?
If AutoCAD question can't you move the geometry closer to 0,0,0? Where was it located in Rhino?
Dimension font size set the dimscale variable to reciprical of layout view scale.
To align is your geometry aligned to xy ucs?
